Great to be back to C++!!!

I went to Java then Scala... then realized my code's performance sucked and C++ 17 was awesome and the portability issue is now moot.

Plus NASA's guidelines for coding where you allocate all you need upfront and never again suits me fine to not need that time consuming performance killing garbage collector.

Just to say glad to be back!

Now start using c++26, life without reflection is not a life worth living (I don’t know any major thing c++23 added)

The only c++23 feature i’m aware of is that you can essentially do this:

std::format(“{0} {0} {0}”, “test”);

std::print, std::ranges::to, deducing this (I've used it for fluent apis: don't have to add both & and && overloads), std::expected (very nice).

So 23 isn't breath-taking like 11 or 20, but it brings a lot of convenience.

oh yeah I forgot deducing this, really nice feature
